The trusty pressure washer is a gardener’s best friend, so it’s a good idea to do some research before buying. These machines are capable of blasting away debris, mud, and plant gunk like no other tool, and they’re also versatile enough to be used on a variety of surfaces including hard, cement and stone pavers, patios, verandas, and driveways, as well as softer materials such as timber and fibro.
Before buying a pressure washer it’s a good idea to work out what you’ll be using it for. If you’re planning to power wash your entire driveway and patio, you’ll need a more powerful engine than if you’re just planning on cleaning a few window sills. There are a range of different machines on the market to suit all needs, so it’s worth working out what you need before committing to a purchase.

Best Pressure Washer Pumps Buying Guide
Before choosing the best pressure washer pump you should consider following options:
1. Water inlet valve: This is an important part of the pump that helps regulate the water flow into the pump. You can find two types of valves: one that is usually mounted on the water source itself, and another that is attached to the discharge hose.
Some pumps have both valves, while others have just one. If the pump has just one valve, it is important that you position it in a way that allows water to flow easily into the pump.
2. Discharge valve: The discharge valve also regulates water flow, but in the opposite direction. This valve is also available in two different models: one that is attached to the pump and another that is mounted on the discharge hose.
The two valves need to be in sync to ensure the right amount of water flows into and out of the pump. If the valves are not in sync, you may end up with an over- or under-pressurized pump.
3. Discharge head: The discharge head determines the maximum water pressure that the pump can produce. You can find two types of discharge heads: fixed and adjustable.
Fixed discharge heads are good for tasks that require a high water pressure, such as cleaning masonry and removing dirt from driveways.
Adjustable discharge heads are better for jobs that need a medium water pressure, such as cleaning windows and washing vehicles.
4. Maximum flow rate: This is the volume of water that the pump can discharge over a period of time. You can calculate the flow rate of a pump by multiplying the GPM (gallons per minute) by the discharge head in feet.
The maximum flow rate is important if you need to use the pump for applications that require a steady supply of water, such as cleaning carpets or washing vehicles.
5. Power source: The power source of a pump is determined by the energy that drives it. There are two types of sources: electric and gas-driven.
Electric-powered pumps use electricity from the local power grid, and gas-powered pumps use either a gas-powered engine or a battery-powered electric motor.
Gas-powered pumps are usually more expensive, but they are very convenient because you can use them anywhere.
6. Power requirement: This is the amount of energy that is required by the pump at any given moment. This can be calculated by multiplying the flow rate by the head in feet.
You can calculate the total power requirement by multiplying the flow rate by the head in feet and then multiplying the result by the GPM.
7. Maximum water depth: This is the maximum height that the pump can discharge water in relation to the water source. This is usually expressed in feet of submergence.
